Description

Technical Field

[0001] This utility model relates to the field of reactor cleaning technology, and in particular to a PET reactor with cleaning function. Background Technology

[0002] During the PET production process, reaction products are very likely to remain on the internal structure of the reactor, such as the side walls, bottom, and stirring device. If not cleaned properly, they will affect reuse. Therefore, in order to ensure the stability of product quality, the reactor must be cleaned after each batch of products is completed.

[0003] Cleaning reactors is a common challenge. Because the inlet of a reactor is relatively small, it is inconvenient for personnel to enter the reactor for cleaning. Most existing technologies use spray pipes to spray water into the reactor to achieve the purpose of cleaning. However, the location of the spray pipes inside the reactor is not easy for the staff to observe, so it is impossible to ensure that the residues on the inner wall of the reactor and the internal stirring device are thoroughly rinsed, which affects the effect of subsequent reactions of substances inside the reactor. Utility Model Content

[0004] To address the technical problem that the spray pipes inside the reactor are inconvenient for workers to view, making it impossible to clean the residues on the inner wall and internal stirring device of the reactor, this utility model provides a PET reactor with a cleaning function.

[0005] This utility model is achieved using the following technical solution: a PET reactor with a cleaning function, comprising a reactor body, a fixed column for support fixedly connected to the outside of the reactor body, an inlet and multiple cleaning ports provided at the top of the reactor body, and an outlet provided at the bottom of the reactor body, a stirring shaft rotatably connected to the middle of the reactor body, and a servo motor coaxial with the stirring shaft fixedly connected to the middle of the top of the reactor body; multiple cleaning ports are rotatably connected to connecting pipes located inside the reactor body, and multiple sets of high-pressure nozzles for rinsing the inside of the reactor body are provided outside the connecting pipes.

[0006] Through the above technical solution, multiple rotatable connecting pipes enable multiple sets of externally fixed high-pressure nozzles to not only rinse the inner wall of the vessel, but also to rinse the stirring shaft and other parts inside the vessel for residue.

[0007] As a further improvement to the above solution, a transmission assembly for driving multiple connecting pipes to rotate synchronously is provided on the outside of the stirring shaft; the transmission assembly includes a drive gear fixedly connected to the outside of the stirring shaft, and a driven gear that meshes with the drive gear is fixedly connected to the top of the multiple connecting pipes.

[0008] Through the above technical solution, the servo motor drives the stirring shaft to rotate, which causes the drive gear fixed to the outside of the stirring shaft to drive multiple driven gears to rotate synchronously, so that the high-pressure nozzles on the outside of multiple connecting pipes can be flushed synchronously, thereby improving the cleaning efficiency inside the reactor.

[0009] As a further improvement to the above solution, the connecting pipe located at the top of the inside of the vessel body bends towards the inner wall of the vessel body, and the connecting pipe located at the bottom of the inside of the vessel body bends towards the discharge port.

[0010] Through the above technical solution, the upper end of the connecting pipe is bent towards the inner wall, so that multiple sets of high-pressure nozzles rotate around the vertical part outside the top of the connecting pipe as the central axis, so that the water jet from the high-pressure nozzles can be rinsed at a variable angle, thereby improving the cleaning effect inside the vessel.

[0011] As a further improvement to the above scheme, multiple sets of high-pressure nozzles are arranged linearly on the outside of the connecting pipe, and each set of high-pressure nozzles consists of two pairs of high-pressure nozzles that are fixed in a staggered manner.

[0012] Through the above technical solution, each set of high-pressure nozzles consists of two pairs of high-pressure nozzles that are fixed in a staggered manner, which can increase the number of rinsing times in the same amount of time, thereby improving the overall cleaning efficiency and quality of the reactor.

[0013] As a further improvement to the above solution, an auger blade is fixedly connected to the bottom end of the stirring shaft, and the auger blade is located inside the discharge port.

[0014] The above technical solution, through the design of the auger blades, can prevent excessive residue from accumulating at the discharge port and causing blockage.

[0015] As a further improvement to the above solution, a high-pressure nozzle for aligning the auger blades is fixedly connected to the bottom end of the connecting pipe.

[0016] With the above technical solution, a high-pressure nozzle is fixed to the bottom of the connecting pipe, which is opposite to the auger blades. This nozzle can wash the rotating auger blades, preventing residues inside the reactor from remaining on the surface of the auger blades and affecting the subsequent reaction effect.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, by arranging multiple staggered high-pressure nozzles on the entire outer side of the connecting pipe, ensures that residues on the upper and lower inner walls of the vessel and other parts such as the stirring shaft are rinsed with equal force. The one-pipe-to-the-end design of the connecting pipe is not only more time-saving and labor-saving than traditional manual rinsing, but also uses fewer parts and has a lower cost compared to existing cleaning equipment.

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Please combine Figures 1-3 This embodiment of a PET reactor with a cleaning function includes a reactor body 1. A fixed column 2 for support is fixedly connected to the outside of the reactor body 1. An inlet 4 and multiple cleaning ports 3 are provided at the top of the reactor body 1, and an outlet 5 is provided at the bottom of the reactor body 1. A stirring shaft 6 is rotatably connected to the middle of the reactor body 1. A servo motor coaxial with the stirring shaft 6 is fixedly connected to the middle of the top of the reactor body 1. Multiple cleaning ports 3 are rotatably connected to connecting pipes 7 located inside the reactor body 1. Multiple sets of high-pressure nozzles 8 for rinsing the inside of the reactor body 1 are provided outside the connecting pipes 7. A transmission assembly for driving the multiple connecting pipes 7 to rotate synchronously is provided outside the stirring shaft 6. The moving assembly includes a drive gear 9 fixed to the outside of the stirring shaft 6, and driven gears 10 that mesh with the drive gear 9 are fixed to the top of multiple connecting pipes 7. The stirring shaft 6 located in the middle of the vessel body 1 is driven to rotate by a servo motor. Since the connecting pipes 7 are rotated in the cleaning port 3 opened at the top of the vessel body 1, the rotation of the drive gear 9 fixed to the outside of the stirring shaft 6 can synchronously drive the multiple driven gears 10 located on the outside of the top of the connecting pipes 7 to rotate. This allows the connecting pipes 7 located inside the vessel body 1 to not only rinse the inner wall of the vessel body 1, but also to rinse the residue of the stirring shaft 6 and other parts inside the vessel body 1.

[0026] Combination Figure 2 and Figure 3The connecting pipe 7, located at the top of the vessel body 1, bends towards the inner wall of the vessel body 1, and the connecting pipe 7, located at the bottom of the vessel body 1, bends towards the discharge port 5. Multiple sets of high-pressure nozzles 8 are arranged linearly on the outside of the connecting pipe 7, and each set of high-pressure nozzles 8 consists of two pairs of high-pressure nozzles 8 that are fixed in a staggered manner. By setting the upper end of the connecting pipe 7 to bend towards the inner wall of the vessel body 1, the multiple sets of high-pressure nozzles 8 located on the outside of the connecting pipe 7 rotate around the vertical part outside the top of the connecting pipe 7 as the central axis, so that the water jet from the high-pressure nozzles 8 can be rinsed at a variable angle, thereby improving the cleaning effect inside the vessel body 1.

[0027] Combination Figure 3 The bottom end of the stirring shaft 6 is fixedly connected to an auger blade 11, and the auger blade 11 is located inside the discharge port 5. The bottom end of the connecting pipe 7 is fixedly connected to a high-pressure nozzle 8 for facing the auger blade 11. By fixing the auger blade 11 to the bottom end of the stirring shaft 6 and setting the auger blade 11 inside the discharge port 5, with its upper end extending beyond the interior of the discharge port 5, it is possible to prevent excessive residues on the inner wall of the vessel body 1 and the components from accumulating at the bottom of the vessel body 1 under the flushing of the high-pressure nozzle 8, thus avoiding blockage of the discharge port 5.

[0028] The implementation principle of a PET reactor with cleaning function in this application embodiment is as follows: Before cleaning, three water pipes connected to the water source are respectively installed on the inner side wall of the connecting pipe 7. Then, the water source is connected, and the water flow will flow from the water pipe into the connecting pipe 7 which is rotatably connected to the cleaning port 3, and then to each high-pressure nozzle 8 on the outer side wall of the connecting pipe 7. At this time, the servo motor is turned on to drive the stirring shaft 6 located in the middle of the reactor body 1 to rotate. Since the connecting pipe 7 is rotatably installed in the cleaning port 3 opened at the top of the reactor body 1, the rotation of the drive gear 9 fixed to the outside of the stirring shaft 6 can synchronously drive multiple driven gears 10 located on the outer side of the top of the connecting pipe 7 to rotate. This causes multiple sets of staggered high-pressure nozzles 8 to rotate around the vertical part outside the top of the connecting pipe 7 as the central axis, rinsing the surface residues on the inner side wall of the reactor body 1 and other internal components. The rinsed residues flow together with the water flow and the high-pressure nozzles 8 facing the auger blades at the bottom of the connecting pipe 7 to the discharge port 5 at the bottom of the reactor body 1.

Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
